The daughter of "Die Hard" acting professional Bruce Willis stepped around New York Town naked earlier this week and then tweeted the images to demonstration Instagram's bare skin policy.
Instagram has removed and won't allow images of erect nipples, even breast cancers heirs and ladies nursing their children.
Willis, 22, outlined that people can publish revealing images and images about weapons and assault but not females showing their erect nipples.
"Legal in NYC but not on @instagram," she had written in her Twitter feed.
NYC police validate that it is lawful for females to walk around the town naked.
She added, "What @instagram won't let you see #FreeTheNipple."
Willis said for publishing images naked prior to this demonstration, Instagram removed her account.
Instagram's terms and conditions state, "You may not publish aggressive, naked, partly naked, discriminatory, illegal, infringing, hateful, adult or intimately effective photos or other content."
